The main objective of organic farming is the preservation of natural resources and agricultural productivity withminimal negative impact on the environment.Organic gardening differs from conventional vegetable production in the system, ways and peculiarities output fightingweeds, pests and diseases.The allelopathy is identified as one of the factors that regulate the growth and distribution of plant communities innatural and cultural agrophytocenoses.For the purpose of organic farming, allelopathy can be an important element in balancing the relationship betweendensity and weeds, pests, diseases and cultivars.Relationships among the vegetable species and varieties in particular mixed stand are not sufficiently explored, whichis a sufficient reason to conduct such a study.
